From left, Abel D. Breed, William Bryant and Eben Smith sit at a small table examining a piece of ore, possibly from the Caribou Mine in Boulder County, Colorado, owned by Breed. Breed holds a magnifying glass in his right hand. Smith and Bryant were both mine superintendents. The Caribou Mine was one of the richest silver mines in the region. In 1873, when President Ulysses S. Grant visited Central City in Gilpin County, silver ingots from the Caribou Mine were used to ; pave the street in front of the Teller House where the president stayed.
